4 Claims.

My invention relates to improvements in heating apparatus, and the same has for its object to provide a radiator of the convector type which is simple in construction, eflicient in operation, and comparatively inexpensive-to manufacture.

Further, said invention has for its object to provide a radiator structure of the sectional type in which the several sections, when connected together, form an enclosed radiator of the convector type.

Further, said invention has for its object to provide a radiator composed of a plurality of cast metal sections having air outlets at its upper front portion separated from each other both vertically and horizontally by relatively thin metal walls or partitions to simulate a grill extending entirely across the front of the radiator.

Further, said invention has for its object to provide a radiator of the type specified in which a more eficient circulation and heating of the air through. the radiator will be obtained.

Further, said invention has for its object to provide a radiator in which the hollow body portion terminates at one end in a thin solid, integral web which, with its lateral extensions, form a plurality of enlarged air outlets in order to insure an active circulation of the air through and the discharge from the structure.

Further, said invention has for its object to provide a radiator of the type specified in which the air to be heated is received at the base of the structure, and after passing upwardly between the sections and heated, is discharged at the upper portion of the structure through outlets each of which is of greater cross-sectional area than that of the vertical portion of it's respectiveair passages provided between the contiguous sections.

Other objects will in part be obvious and in part be pointed out hereinafter.

To the attainment of the aforesaid objects and ends my invention consists in the novel features of construction, and in the combination, connection and arragement of parts hereinafter more fully described and then pointed out in the claims.

In the accompanying drawings- Figure 1 is a front elevation showing one form of a radiator constructed according to and embodying my said invention;

Fig. 2 is an end view thereof;

Fig. 3 is a front edge view of an intermediate section;

Fig. 4 is a section on the line 6- 3 of Fig. 3;

Fig. 5 is a section on the line 5-5 of Fig. 3;

Fig. 6 is an enlarged side view of a center section,

Fig. 7 is an enlarged detail front view of the upper front portion showing several connected sections and the arrangement of air outlets therein, and

Fig. 8 is an enlarged front view of the upper portion of the radiator showing the air outlet structure.

In said drawings 80 designates a radiator of the convector type comprising a plurality of correspondingly shaped intermediate sections H, and end sections l2 provided with legs l3. The several sections are provided at their upper and lower rear corners with apertured hubs l4, l5, respectively, to receive nipples M l5 whereby the said sections are communicatively connected together and to the supply pipe I l and return pipe is communicating with a source of fluid heating medium. The several sections, when duly assembled, form a radiator presenting the appearance of an enclosed or cabinet type radiator which is provided at its base with air intake openings l 23, and at its upper forward end with a series of air outlet openings extending across the entire length of the radiators in the form of a grill-like structure 2 i.

Each radiator section ll, I2 is of substantially rectangular outline and comprises a relatively thin, hollow body portion 22 having at its upper forward portion tapered and terminating in a thin, solid integral web 2t disposed in a vertical plane coinciding with the median line of the section. 2% denotes short horizontal fins of substantially the same thickness as the web 23, which fins extend laterally from the opposite sides of the vertical web 23, and form, with the corresponding fins of the adjacent radiator sections, superposed rows of rectangular air outlet openings 25, separated from each other by relatively thin, solid dividing walls, and presenting the appearance of a grill extending entirely across the front of the radiator.

The opposite sides of the hollow body portion 22 are provided with a plurality of vertical fins 26 which extend longitudinally of the radiator section and have their upper ends curved and directed outwardly and terminate at the front of the radiator section as the short horizontal fins 2%. The fins 26 of each section register with the corresponding fins of the adjacent radiator sections and form therewith a series of passages 2i through which the air entering at the open base it of the radiator and the air inlet opening 26 at the back of the section just above the lower nipple hubs [5, may pass and become heated and thence be discharged at the upper forward portion of the radiator through the outlet openings 25.

Each radiator section is provided at its top and upon its opposite sides with peripheral ribs 28 which are interrupted at the base to form the intake openings I 9, and at the rear side directly above the lower nipple hub Hi to form the additional air intake openings 20.

To insure the proper entry of air into the passages 21 the lower ends of the fins 26 become progressively shorter as they near the rear edge of the section to provide an enlarged intake portion 29 between the several sections.

The rear edges of certain of the radiator sections as, for example, the end sections l2 are provided with short, rearwardly projecting lugs 3D, in order to prevent the rear side of the radiator from coming intodirect contact with the wall of the room or recess which would prevent or materially interfere with the admission of air to the air intake 20. I It is to be noted that by reducing the thickness of the hollow body portion of the radiator at the upper, forward portion thereof and terminating the same in relatively thin, vertical rib, centrally of the radiator section an outlet opening is provided of greater cross-sectional area than that of the vertical passage with which said outlet communicates, thereby insuring an outlet of sufficient size to permit of the free and unrestricted discharge of the air which has been heated and expanded in its passage through the radiator.

Having thus described my said invention what I claim and desire to secure by Letters Patent is:

1. A radiator comprising a plurality of communicatively connected fiat, hollow sections having air passages between the same, said hollow sections terminating at their upper portions in solid, vertical webs of reduced thickness, and horizontally-extending fins forming with the vertical webs and fins of contiguous sections outlets of greater cross-sectional area than that of said air passages for the discharge of heated air.

2. A radiator comprising a plurality of communicatively connected fiat sections each including a hollow body portion and air passages between said sections; said hollow integral body portions terminating at their upper portions in solid, vertical webs of reduced thickness and horizontal fins extending from the opposite sides of said webs registering with the horizontal fins on the webs of contiguous sections and forming therewith a plurality of rows of enlarged outlets for the discharge of heated air.

3. A radiator comprising a plurality of communicatively connected fiat sections each including a hollow body portion and air passages between said sections; said hollow body portions terminating at their upper portions in relativelythin solid, vertical webs and horizontal fins extending from the opposite sides of said webs of uniform thickness therewith and registering with the horizontal fins on the webs of contiguous sections and forming therewith a grill-like portion extending across the front of the radiator and comprising a plurality of horizontal and vertical rows of enlarged outlets for the discharge of heated air.

4. A radiator comprising a plurality of communicatively connected fiat hollow sections each including a plurality of laterally-projecting ribs upon opposite sides thereof extending lengthwise of the section and registering with the corresponding ribs of. continuous sections and forming therewith air passages having intake portions adjacent the bottom of the radiator; each of said hollow sections terminating at its upper forward portion in a solid, vertical web of reduced thickness disposed centrally of the section 'and horizontally-extending rib portions forming with the vertical webs and rib portions of contiguous sections enlarged outlets communicating with said air passages for the discharge of heated air.
